Oh man when my friends and I really began smoking often, we didn't have a piece and we don't know how to roll so we would just walk/drive around smoking out of an apple I got my friend a bowl for Hannukah (that's what we usually use, but tonight I'm by myself) but haven't had the money to buy my own yet, but considering I just resorted to a potato, I think I'm doing that tomorrow haha.
Try making something. Mess around with socket wrenches or bottles. A household object that makes a good bowl is a salt shaker top. toke onnnnnnnnnn
